My invention relates to dumping vehicles and, in particular, to avehicle Awhich is adapt-- ed to dump on either sideandto the rear.Specifically, the invention comprises a novel method and means foreffecting'` a tilting movement of a dumping body.

According to present practices in the dumping vehicle art, three-waydumping is effected by supporting the dumping body at four points, forexample, adjacentthe corners. Arrangements are made for receiving thecorner supports, whichgenerally take the form ofhingepins, intoassociated cups or sockets.' By locking anyv two adjacent pins to theirsockets,pit is possible to tilt the body about an axis passing throughsaid pins, the remaining .pins being free to rise from their sockets asthe body is tilted. Y The hinge pins now in use include knuckles` andlpivot pins,

both of which must be machined. This type of hinge has proved to havecertain objectionable features, one of which is that after ya certainamount of wear, the body, when tilted, tends to swing oif of the pinstoward the V2,5 low side. 2 This Aresults in the failure of the pins onthe highV side to reenter their cups or sockets. If the body isloweredwithout properly seating the hinge pins, it is obvious that on dumpingtoward the other side, the

V30 bodywill be thrown off the vehicle chassis.

f one tothe vehicle frame, so as to constitute a rigid hinge whichpermits dumping the body toward Vthe side or tov therear. The lowerhinge member has the form of a hook or toroidal bearing extending fromthe vehicle chassis.l The lupper hinge member is a casting secured tothe dumping b ody and has a downwardly projecting yokeor ring portionresting on and extending around the hook 4or toroidal bearing".` The'two lmem- .45 bers have bearing surfacescorrespondingly COMPANY, OFYOUNGSTOWN, OHIO, A CORPORATION i shaped substantiallytoroidalrso as tol l' mit the upper hinge member to rotate upon the lower in two planesnormalto each other.

The invention eliminates'all lostmotion between the body anditssupports,sincfe the upper hinge Vmember is rigidly secured to the body.There is no difficulty experienced in maintaining thehinge `members inproper alinement, as the body isgbeing lowered. It will thusbepractically impossible to throw the body off the chassis, because offailure of the `hinge members to cooperate properly as' the body islowered. The invention also reduces the cost yof manufacture since allmae chine work is eliminated andv` only the. two one-piece castings arenecessary tol constitute the hinge. Y

I also make provision whereby the weight i of the body is taken offthebearing.l members as the body is lowered. A, strong support is thusafforded for the body 'and the bea-ring surfaces are relieved of theweight ofthe body, which would cause excess wear thereof. Anotheradvantage of the, invention isthatit makes it possible to space thehinges further apart than is possible with the present type. As aresult, vit is possible to employ a'longer stroke of the hoist mechanismVand to move the latter nearer to the front of the body toward the idealposition, namely',fthe"cen ter of the body. s, 1 't For a completeunderstanding of theinvention, reference 'should bey made to theaccompanying drawings'llustrating a present preferred ,embodimentthereof. The drawings are intended merely as illustrations of one of thehinge-,flocking thereon from oneside ofthe truclito which it is applied,

invention is adapted for use in connection with a vehicle such as amotor truck, having a chassis illustrated in part at 10. Upon thechassis, I mount front and rear cross members,

Vof which the rear cross member is shown at 11. To each end of the crossmembers, I secure a lower hinge member-12 having a bearing or hookportion 13 by means of rivets 14. The bearing surface of the hookportion is in the form of lan anchor ring or toroid and is rounded intwo directions. A shoulder 15 1 is formed integral with the casting 12,for a purpose which will be described hereinafter.

The casting 12 also has a cap 16 shaped to conform to the upper surfaceof the cross member 11 and'resting thereon.

Cooperating with the lower hinge member 12 is a downwardly projectingupper hinge member 17 which has a yoke or ring portion 18 of toroidalshape, resting on and extending partly around the hook 13 of the lowermember 12. The castings 12 and 17 are ribbed and flanged for additionalstrength and rigidity. The upper hinge member 17 directly supports thevehicle body which hasside Z-bars 19 at its bottom which are riveted tothe hinge member 17 by the rivets 20. The casting 17 4J) is providedwith an opening 21 for a purpose to be described later.

The casting 17 has a flat surface 22 adjacent the upper end thereof forcooperation with the shoulder 15 on the lower casting 12. Thus, when thebody carried on the Z-bars 19 is fully lowered, as shown in Figure 2,the weight of the bodyis transmitted from the surface 22 to the shoulder15 and thence to the cross member 11 and the vehicle chassis.

Referring again to the lower casting 12, and particularly to Figure 3,this member has a sleevev 23 for receiving a locking bar 24. The bar 24is adapted to pass through the opening 21 in the upper casting 17 andthrough a corresponding opening 25 near the end of the'hoo-k portion 13of the casting 12. A sleeve 2.6 is riveted tol the rod 24 for enteringthe openings 21 and`25. ASuitable oper- Y- ating means (not shown) isprovided for the locking bar 24, preferably of the type described in mycopending application, Serial No. 257,707, filed February 28, v71928,.for hoistmechanism. T y

When it is desired to dump the truck body toward the rear, the hinges atboth'ends of the rear cross member 11 are locked by the bar 24, which isof such length that it overlies the yokes 18 of the castings 17 atopposite sides of the body. When the body is raised by any suitablehoist mechanism, the corresponding hinges at the front of the vehiclebeing free to rise, the body will be tilted about an axis passingthrough the center of the toroidal portion 13 of the casting 12. Theyoles 18 of the front hinges, which are identical with the rear hinges,rise from their toroidal bearings as the body is tilted. The opening 21in the casting 17 permits the latter to rotate, although the locking barpasses therethrough. The body' may be lowered in the same manner,whereupon the yokes of the front hinges reengage their toroidal bearingsand the body is supported by the engagement of the surfaces 15 and 22.The tilted position of the member 17 is shown in chain lines inFigure 1. y

When it is desired to dump the truck 'toward they side, the locking bar24 and its counterpart in the front cross member are shifted toward theside to which the body I is to be. dumped. The hinges on that side ofthebody are thus locked while those on the opposite side are freed.Application of hoisting force nowcauses the body to tilt about an axispassing through the 4center of the yoke portion 18, as shown in Figure3. The yoke portions on the opposite side of the body rise from theirtoroidal bearings, as previously described in the rear dumpingoperation. When the dumping has been completed and the body is againlowered, the yoke portions 18 enter their toroidal bearings and theweight of th-e body is again evenly distributed on the ends of the crossmembers. The side dumping position of the member 17 is shown in chainlines in Figure 2',

It will be obvious from the foregoing'description that the inventionprovidesa strong and rigid hinge consisting of but two parts,

which are so designed as to permit rotation lof the upper hinge memberin the lower member in two planes which are at right angles. Since thebody is at all'times supported on at least two of the castings 17, therewillbe no side slippage` of the body when tilted. As the body islowered, each of the yokes 18 on the high side will be guided directlyinto, their toroidal bearings. Accidental throwing 0H of the body, dueto a failure ofthe hinges ...11.20

to engage properly, is thus avoided and safety ofoperation of thevehicle is much increased. In addition, the weight of the body istransmitted directly to the vehicle frame at all iio times, except whendumping, in whichv case tively low cost and the fact that they requireno machining,`eliminates an additional item of expense encountered inthe manufacture of present tylpes of hinges.

Although have described and illustrated but a single present preferredembodiment of the invention, I do not intend to be limited to thespecific details of the structure shown, since the invention may beembodied in other forms and any changes in the embodiment illustratedmay be made within the spirit of the invention land are not to beconsidered as departures from the scope of the appended claims.

I claim:

1. A hinge for a tilting vehicle body including a frame and a transversesupporting member thereon, comprising a castlng secured to saidtransverse member, having an outwardly projecting, upstanding, open-top,j

hook portion thereon, and a casting secured to said body having anopen-bottom yoke portion projecting downwardly and outwardly, resting onand partially encircling said hook portion, and adapted to be supportedin'said hook portion for rotation in the plane of said transverse memberand in a plane perpendicular thereto.

2.- A hinge for a tilting vehicle body supported on a frame, comprisinga member on said frame having an outwardly projecting, upstanding,open-top, hook portion thereon, and a member on said body having anopenbottom, yoke portion projecting downwardly and outwardly of thebody, resting on and partially encircling said hook portion and adaptedto be supported in said hook portion for rotation thereon in twoperpendicular planes.

In testimony whereof I have hereunto set my hand.
